Single-Wavelength mode is the detector's default mode of operation.
The detector supports monitoring of a single wavelength from 190 nm to 700 nm, settable in 1-nm increments on channel A.
In this mode, the detector automatically engages the optical, second-order filter for wavelengths 370 nm and above and removes it for wavelengths under 370 nm. This filter blocks unwanted UV light from striking the diffraction grating and interfering with absorbance detection above 370 nm.
When using the detector in this mode, you can configure the additional parameters listed in the following table and set up an Events table for the detector.
Table 1.
Single-Wavelength mode configurable parameters
| Parameter |
Description |
| Lamp |
Set the detector's lamp to On or Off |
| Data rate (Hz) |
Specify a sampling frequency up to 160 Hz (single channel, 2 Hz for dual channel) |
| Wavelength A (nm) |
Specify a wavelength for channel A, from 190 nm to 700 nm, settable in 1-nm increments
Note: If the detector is in Dual-Wavelength mode, the value of Wavelength B also appears.
|
| Filter time constant (s) |
Program a filter time. Options are No Filter, Slow, Normal, Fast, and Custom (see Filtering noise for detailed information about this parameter, these setting options, and the different effects produced). |
Autozero (two options):
- Autozero on Inject Start
- Autozero on Wavelength Change
|
Set when to autozero (resets the detector offsets) |
